    摘要: A gaming machine including a controller coupled to a 3D display that displays true 3D or virtual 3D imagery associated with a basic or a bonus wagering game. 3D displays can display true 3D imagery or virtual 3D imagery that is displayed in 2D but perceived by the viewer to be 3D. True 3D displays include a volumetric 3D display, a multi-layer display, and a holographic display. Virtual or stereoscopic displays include a lenticular display employing cylindrical or spherical lenslets, a parallax illumination display employing light lines to create a parallax effect, or non-autostereoscopic displays requiring a special viewing aid to complete the 3D effect.

    摘要: A holographic display device and a method for generating a hologram are disclosed.
    The holographic display device generating a hologram includes a storage unit (180) and a control unit (190). Herein, the storage unit stores at least one look-up table each storing a partial size (400, 600) of a full size (300,500) sub-hologram for reconstructing object point (OP), wherein the object points (OP) are included in a scene reconstructed by the generated hologram. And, the control unit uses at least one look-up table each having the partial size, so as to calculate hologram values for the sub-holograms for reconstructing object points (OP), wherein the object points (OP) are included in the scene, and then the control unit generates the hologram by overlapping the hologram values of the sub-holograms.
